Map shows varying motion of the plates, which represent a multitude of factors influencing land quakes, from oceanic plate-shifts and rifts.

-Article: Quakes Cannot Be Predicted.
-Earlier Summary: The use of tensor analysis, matrix theory, group theory, topology, and theory of stochastic processes must be involved in translating points of probability; but I actually do believe that earth's renewal is random; & perhaps not even an ice-age would slow earth natural formation of crust.
Note: I'm sure that there's more than one 'double-negative' here; but one might ask, does earth "feel" for humans? We're visitors; mountains grow & stay.
